Colorado Building Permits by Jurisdiction
No comprehensive statewide building code; counties/municipalities adopt their own I-codes. State mandates exist for electrical, plumbing, and energy (jurisdictions updating codes must adopt the 2021/2024 IECC).
Jurisdiction-by-jurisdiction verification is in progress — pages marked “being verified” show the statewide baseline until confirmed locally.
